About Ductile Iron Pipe Fittings
Ductile iron pipes are cast iron piping used for the transmission of gas or potable water, often underground. Ductile iron pipe fittings connect the pipes and, like the pipes themselves, may or may not be lined on the inside with graphite or resin and coated or encased on the outside with other materials which can help to prolong pipe lifespan. Zoro carries hundreds of iron pipe fittings, including ductile iron couplings, ductile iron tees, ductile iron concentric reducers, ductile iron caps, and ductile iron elbows, to name a few. Items vary by fitting size, diameter, maximum pressure, temperature range and other considerations. For non potable water and gas transmission options see our black pipes and black pipe fittings.
